The Nippon Steel & Sumitomo Metal Corporation has been selected as one of the top 100 companies in the world by Thomson Reuters (Head Office: New York) for two consecutive years at the “Top 100 Global Innovators 2013” awards, which recognizes the most innovative companies and research bodies in the world.

Following on from the previous year, our company continues to be the only company selected from the primary metals industry, which also encompasses the steel industry.

Of the four selection criteria, the company was particularly highly regarded in terms of the “volume” of patents held and its “global” characteristics. The compa-ny also scored highly in terms of its “success” rate and the “influence” as to the degree to which its patents had been cited elsewhere.The Nippon Steel & Sumitomo Metal Corporation exhibits an excellent balance in meeting all four criteria, revealing the company’s advanced level of technology and high global presence.

High-tensile / Excellent Quality HAZ Toughness Plate

Energy Solutions from Nippon Steel & Sumitomo Metal Corporation Group


Benefits of use

Improvement of HAZ toughness technology

● The needs of high tensile steel are growing up as the size of facility increases.● NSSMC has wide range Pre-Qualification material with high toughness for offshore structure using

advanced technology.● NSSMC has supplied offshore structural steel for various projects all over the world.● NSSMC has applied the TMCP(*1) process to offshore structural high tensile steel with excellent

weldability and HAZ(*2) toughness for the first time in the world. (*1:Thermo Mechanical Control Process. *2:Heat Affected Zone)● The shift to high tensile steel leads the reduction in the size and weight of steel structure. As the result, it is possible to reduce “Distribution and installation cost” while mounting equipment.

❶ Compatible with the needs in place for high strength structures

● In addition to Gr50 and Gr60 steel plates speci�ed by API standards, we have newly developed Gr80 steel plates, being the �rst in the world to put it into practical use.

❷ Weight reductions● Allows for capacity in TOPSIDE-loaded equipment.

❶ Excellent TMCP technology

❷ Improvement of HAZ toughness

❸ Good weldability

Advantages

● Displays around 5 to 10 times the corrosion resistance of regular steel and stainless steel against high-temperature, high-concentration sulfuric acid and high-tempera-ture, high-concentration hydrochloric acid.

● Offers economic bene�ts over stainless steel.● Wide lineup that encompasses everything from hot-rolled and cold-rolled steel

sheets to steel piping and welding materials.● Features a lineup of dedicated welding materials, making welding possible under

the same conditions as ordinary steel of the same strength.

S-TEN1 is a sulfuric acid and hydrochloric acid dew-point corrosion-resistant steel developed by NSSMCusing proprietary technology.

● S-TEN1 exhibits the best resistance to sulfuric acid and hy-drochloric acid dew-point corrosion found in the �ue-gas treatment equipment used with coal-�red boilers, waste incineration plants, etc. (This steel has the �nest application record in the �eld of thermal power generation and waste incineration plants, according to surveys conducted by NSSMC)

● S-TEN1 exhibits the best resistance to sulfuric acid and hy-drochloric acid dew-point corrosion found in hydrochloric acid pickling, industrial sulfuric acid and other tanks.

● S-TEN was awarded the Ichimura Industrial Award Achive-ment Award in 2007.

The Nippon Steel & Sumitomo Metal Corporation began producing and selling H-shapes in 1959.

Since then, it has consistently produced high quality H-shapes and it is used in structures all over the world.

With the recent increase in world energy demand, the company has been activity in also focusing its attention to fields relating to energy development for the sale of its products.

NSHYPER BEAM is a high quality rolled H-shapes which acts as an alternative to welded H-shapes from the sheer variation in sizes available. The bene�ts of non-welded steel (no need to fabri-

cate / no need welding inspections / high quality) have received much praise, and this has been widely adopted in the form of H-shaps for steel frames in the natural resource and energy �elds.

NSSW’s Seamless FCW(Copper coating) Conventional Fold Type

When NSSW’s SFW is used, the life of the tip is about 3.5 times as long as instances where the conventional fold type is used. (When NSSW’s SFW is used, the abrasion of the tip is about 1/3.5.)

Reasons the life of the tip is so long are as follows:a) The surface of NSSW’s SFW is plated with copper and, therefore,

friction is small.b) The cross-sectional shape of NSSW’s SFW is one of point symmetry.

Therefore, the wire is fed out straight.

Tensile properties at room temperatureComparison of Ni contents & pitting resistance

N08825 offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. Alloying Nickel content to 40mass% exhibits proven resistance to chloride stress corrosion cracking. It also resist to intergranular attack caused by welding, and to pitting / crevice corrosion caused by chloride with hostile sour gas condition.

■Main features of N08825

N06625 is a high Molybdenum, Niobium stabilized Nickel base super alloy with excellent resistance to localized corrosion, high temperature oxidation resistance and high strength. It resists stress corrosion cracking due to 62mass% nickel with outstanding resistance to pitting / crevice corrosion owing to 9mass% molybdenum.


N10276 is an extra low carbon-nickel base super alloy with high 15mass% molybdenum. It has superior corrosion resistance to a wide variety of environments, especially reducing media. It is widely used in hostile sour gas processing and production.
